Place the digits 1-5 once each in every row, column, and irregular region.
Digits connected by a white strand have consecutive values. Digits connected by a black strand are in a 2:1 ratio.
Solution code: Row 1

This might have been the best coloring puzzle I've ever done. When I started doing sudoku I was even a bit confused about what people mean by "coloring puzzle" and what counts as one. This can serve as the quintessential coloring puzzle that shows beginners why they want to think of coloring as a central technique. It's absolutely beautiful, and totally shows (like people wrote in the comments) that the challenge in coloring puzzles, which is not present in normal "write numbers down" type of sudoku, is to choose which cells to use to "define" the colors. After solving this, I finally feel I "understand" coloring :).

3 1/2 minutes for this one. I think I landed on a good place to start colouring right off the bat, which helped!

Probably my favorite small irregular puzzle! This was a blast

Incredible how much the difficulty varies depending on where you start the coloring … I was completely lost twice and started Ober and then - starting from another box - finished it in under 10 minutes.

Nice - I usually avoid colouring and use letters instead, for easier scanning, but here I had to use both :-D

After a couple of uncertain starts solved it in 18 minutes. Shouldn't have started it just before going to bed. :)
Fun colouring puzzle tho.

This one is all done with colouring before any numbers appear!
Thanks
